GeneDx RCV000376782 SCV000329837 pathogenic not provided 2018-03-05 criteria provided, single submitter clinical testing The R816X nonsense variant in the NF1 gene has been reported previously in association with neurofibromatosis type 1 (Bahuau et al., 1998; Fahsold et al., 2000; Ko et al., 2013). This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Therefore, we consider this variant to be pathogenic.

Invitae RCV000497042 SCV000628443 pathogenic Neurofibromatosis, type 1 2020-01-07 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg816*) in the NF1 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been reported in several individuals affected with neurofibromatosis type 1 (NF1) (PMID: 9150739, 18484666, 15146469, 23668869, 10712197) and in a family with neurofibromatosis Noonan syndrome (PMID: 9475595). It has been also reported in an individual with NF1 and malignant peripheral nerve sheath tumor (PMID: 19142971) and in an individual with NF1 and pheochromocytoma (PMID: 25403449). ClinVar contains an entry for this variant (Variation ID: 280055). Loss-of-function variants in NF1 are known to be pathogenic (PMID: 10712197, 23913538). For these reasons, this variant has been classified as Pathogenic.
